Furthermore, the Green Bay Packers allowed 30 TD passes last season, tied for fifth-most in the NFL, and their safeties recorded absolutely no interceptions.

The Packers know their pass defense needed to improve for 2014 and made a big move by selecting safety Ha Ha Clinton-Dix with the 21st pick in the first round of the NFL draft. Clinton-Dix is expected to make an impact this season, but so far in training camp a familiar face has stepped up.

Davon House, who has started 10 games combined over the last two seasons, is making an impression, potentially giving the Packers three starting-caliber cornerbacks in House and incumbents Sam Shields and Tramon Williams.

“Davon House is clearly having his best year as a pro, coming off his offseason,” Packers coach Mike McCarthy said. “He's a big, long, strong cornerback; love that whole secondary.”

House, in his fourth year from New Mexico State, was on pace in 2012 to start before he suffered a shoulder injury during preseason sidelined him for the first six weeks of the season. He has been a backup since then but now may be pushing for more playing time.

“Davon had an unfortunate injury in San Diego,” McCarthy said. “Everyone thought that was his time. He was raw when came here; seeing natural progression.”

Burnett sitsSpeaking of the secondary, safety Morgan Burnett tweaked his ankle early in practice Wednesday and didn’t return.

Raji off to great startDefensive tackle B.J. Raji is making an early impression in camp, terrorizing offensive linemen. Knowing the Packers need to get a new center ready for the season, McCarthy is pleased with what he sees.

“B.J.'s in great shape,” McCarthy said. “If you ever want to get a center ready, he's your guy.”

J.C. Tretter is working with the No. 1 offense at center for the Packers and getting chances to go against Raji in practice. Since Tretter didn’t play a game last season he needs as much work as possible.

“He needs every rep,” McCarthy said. “It's not going to look clean, our team isn't clean. He needs this work.”

Extra points—McCarthy on second-year tight end Brandon Bostick: “He's bigger, stronger; needs to stay healthy.
